Definitions

  • the disclosure relates to a connector for a fluid line and to a connecting assembly comprising such a connector and a connecting branch.
  • the disclosure additionally relates to a method for producing a connector.
  • connection of pipes, hoses, connecting branches or other fluid lines is common, for example, in the automotive industry, the utilities industry or in ventilation engineering.
  • the connection is realized with a connector which can be connected in a fluid-tight manner, for instance, to a fluid line on the one hand and to a connecting branch on the other hand.
  • Such connections oftentimes must meet defined requirements, for instance in terms of their compressive strength, leak tightness, temperature resistance and/or mechanical stability. These requirements can be important in terms of the safety of an installation, in particular when such connections are used, for instance, for the connection of fuel tanks or in cooling water circuits of motor vehicles. Furthermore, easy handling of the connector is desired in order to shorten the assembly time and avoid instances of incorrect assembly.
  • One object of the disclosure is to provide a connector for connecting a fluid line to a connecting branch, which connector enables a quick and easy assembly and meets enhanced requirements regarding the compressive strength and leak-tightness of the connection.
  • One object of the disclosure is additionally to provide a connector assembly comprising such a connector and a connecting branch, which connector assembly enables a rapid and reliable connection of the connector to the connecting branch, and a method for producing a connector.
  • a locking device having a locking housing and a locking element is provided in the region of the first opening.
  • the locking housing encloses the connector housing with respect to the fluid duct in the peripheral direction such that an, in particular peripherally circumferential, annular gap, which is open to the first opening, is formed between the connector housing and the locking housing in order to receive a substantially cylindrical connecting branch.
  • the locking element juts with at least one holding portion in an elastically resilient manner into the annular gap.
  • the locking housing is a component which is separate from the connector housing and which, at least in the longitudinal direction of the fluid duct, is fixed to the connector housing in the region of the first opening.
  • the connector thus consists of at least three components, a connector housing and at least one locking device respectively comprising a locking housing and a locking element. Since the locking device, in particular the locking housing, is not part of the connector housing, it can be produced separately, whereby the production of the individual parts is simpler. Moreover, the locking device can be separately adapted and dimensioned to the respectively needed requirements. In particular, the locking device can be produced from other materials than the connector housing, so that a further adaptation to the generated loads or the desired requirements, for instance a weight reduction, can be made.
  • the annular gap and the locking device can be configured such that a slipping-on and fixing of the connector onto previously used connecting branches which have a holding geometry, such as a depression for the reception of, and/or a circumferential collar for the application of, the holding portion of the locking element is possible.
  • connection of the locking housing can be realized differently.
  • the locking housing is fixed to the connector housing via a positive and/or integrally bonded connection.
  • a positive connection can be realized, for instance, by interacting projections or flanges on the locking housing and on the connector housing.
  • the projections or flanges are configured protruding radially outward or radially inward.
  • the connection can be a latching mechanism, wherein on the locking housing or on the connector housing are provided latching lugs, and on the connector housing or on the locking housing are provided latching projections onto which the latching lugs latch in the longitudinal direction.
  • latching mechanism enables a toolless fastening of the locking housing to the connector housing, so that the assembly of the connector is simplified.
  • the latching projections can be formed by a peripherally circumferential flange.
  • means for securing the locking housing to the connector housing in the peripheral direction can be provided, so that the alignment of the locking device on the connector housing is secured.
  • the means can be formed by tooth systems which are provided on the locking housing and on the connector housing and which, for instance, intermesh when the locking housing is fitted on the connector housing.
  • the locking housing can have at an end facing away from the first opening of the fluid duct a radially inwardly jutting collar, which, in particular, is fixed to the connector housing.
  • the collar closes the annular gap in the longitudinal direction and thus forms, for instance, a stop for the connecting branch, so that the latter can be inserted only to the point where the holding geometry is located before the recesses and the holding portions of the locking element can cooperate with the holding geometry.
  • the annular gap can have transversely to the longitudinal direction a constant width. It is also possible, however, for the annular gap to at least in part taper, in the longitudinal direction of the fluid duct, away from the first opening. For instance, a portion directly adjoining the first opening can taper, whereby an inlet guide for the connecting branch is formed. It is also possible, however, for the annular gap to taper in the region of the bottom of the annular gap.
  • the connecting branch can be clamped and/or centered upon insertion into the tapering portion.
  • That inner side of the locking housing that is facing toward the connector housing is at least in part configured such that it tapers conically away from the first opening.
  • the connector has, for instance, a constant external diameter, whereby this is easy to produce.
  • the conical shape of the annular gap is provided only by the shape of the locking housing to be separately produced.

  • the seal is arranged in the annular gap and thus securely protected even when the connecting branch is not inserted.
  • the seal is arranged in a peripherally circumferential groove, so that a displacement in the longitudinal direction is securely prevented.
  • the opening-side end of the connector housing can lie in one plane with the first opening of the connector. These lie, however, in different planes, so that the opening-side end or the first opening of the connector projects in the longitudinal direction, whereby the insertion of the connecting branch could be simplified.
  • the locking element is preferably a clamp, which at least in part encloses the locking housing in the peripheral direction and juts with the at least one holding portion from a radial outer side into the annular gap.
  • the clamp lies, for instance, in a peripherally running groove, in which the clamp is securely held.
  • the locking element can be a metal clamp, which is easy to produce and has a long working life.
  • the locking element is movable between an assembly position, in which the at least one holding portion does not engage in the annular gap or engages therein only to the point where it does not cooperate with the holding geometry of the connecting branch, and a locking position, in which the at least one holding portion engages in the annular gap.
  • the locking element has at least two holding portions, which are arranged, in particular, evenly distributed in the peripheral direction.
  • the connector is held on the connecting branch such that it is evenly distributed in the peripheral direction, so that a tilting of the connector, for instance under a tensile force acting eccentrically on the connector, is prevented.

  • a locking device can be provided also at the second opening.
  • a connector assembly for a fluid line comprising a previously described connector and comprising a connecting branch which has a peripherally circumferential connector portion, wherein the connector portion juts into the annular gap and has at least one holding geometry, which cooperates with the at least one holding portion of the locking element and fixes the connector and the connecting branch, at least in the longitudinal direction of the fluid duct, relative to one another.
  • the connector is slipped with the annular gap onto the connecting branch. After this, the connector is fixed to the connecting branch by an engagement of the at least one holding portion with the holding geometry.
